A novel two-dimensional cadmium(Ⅱ)-nickel(Ⅱ) bimetallic host clathrate, [Cd{NH₂CH₂CH₂OH}2Ni(CN)₄]ㆍ3C?H?NH₂ㆍH₂O, 1, has been synthesized and structurally characterized by X-ray single crystallographic method. The clathrate 1 crystallizes in the monoclinic system, space group P2₁/c with a = 14.370(3), b = 7.728(1), c = 28.172(4) A, β = 97.58(1)°, V = 3101.1(9) A³, Z = 4. The host framework of the clathrate 1 is built of the cyanide bridges between octahedral Cd(Ⅱ) atom and square planar Ni(Ⅱ) atom. The octahedral Cd atoms ligated by two 2-aminoethanol molecules and four cyanide ligands bridged with square planar Ni atoms. The Ni atoms bridges to four Cd atoms via cyanides is made up of puckered quadrangles of composition {CdNi(CN)₂}₂, all edges are shared. This cyanide bridges form an infinite two-dimensional host networks stacking along b axis. 2-Aminoethanol ligands bond to Cd atom through N atom as a monodentate ligand in the axial position and four cyanides take an equatorial plane with all in trans-configurations. The aniline guest molecules and water molecules are located in between the host layer sheets, respectively.
